From the above foods; oil, bread, steak, chicken, butter and pretzel, only 2 contain lots of carbohydrates. Colour the bread and the pretzel.
When oxygen is absent, anaerobic respiration occurs ('an' means without).
Answer: Cyanobacteria, oxygen
Cyanobacteria also known as Cynophyta and blue green algae. It is a phyllum of bacteria that produces it's own food like plants by the process of photosynthesis. It is found in freshwater lakes, damp soils, oceans, moistened rocks and even in animal fur. The purple sulfur bacteria belongs to the group of Proteobacteria. It is an anaerobic bacteria. It is found in hot springs, and stagnant water. It is a photosynthesizing bacterial strain like Cyanobacteria but it does not utilize water to be reduced in the photosynthesis process like in Cynobacteria, to produce oxygen.
Hence, only the <u>Cyanobacteria</u> are capable of releasing <u>oxygen</u>.
